Hello, After upgrading from linux-image-6.12.107+deb13-amd64 to linux-image-6.12.111+deb13-amd64, the built-in keyboard of my laptop no longer works at the LightDM login screen. With 6.12.107 everything works. Hardware - ASUS ROG Strix G18 G814FP, BIOS G814FP.316 (05/14/2026) - Keyboard: ASUSTek "N-KEY Device", USB ID 0b05:19b6, handled by hid_asus System - LMDE 7 (Debian 13 based), using the official Debian kernel packages - LightDM + slick-greeter, Cinnamon, X11 - NVIDIA driver 610.43.03 (out-of-tree, DKMS). Note that the hid_asus error below is logged at ~2.0 s, before the nvidia module loads (~4.4 s). Symptoms with 6.12.111 - The keyboard works in GRUB, but not at the LightDM login screen (I have to use the on-screen keyboard to log in). - After logging in, the keyboard works normally, except Fn+F2/F3 (keyboard backlight brightness). - With 6.12.107 the keyboard works everywhere, including Fn+F2/F3. Kernel log Present only in 6.12.111, right after hid_asus binds to the device: [ 2.008836] asus 0003:0B05:19B6.0003: Fixing up Asus N-Key report descriptor [ 2.009349] asus 0003:0B05:19B6.0003: using HID for asus::kbd_backlight [ 2.018672] asus 0003:0B05:19B6.0003: Asus failed to request functions: -75 [ 2.018684] asus 0003:0B05:19B6.0003: Failed to initialize backlight. In 6.12.107 the same sequence appears without the last two lines. There are no USB disconnect/reset events for usb 3-1 in either kernel. The other ACPI/WMI errors (nvidia-wmi-ec-backlight AE_NOT_FOUND, unresolved BPWM/GPP symbols) appear in both kernels. Workaround Booting 6.12.111 with modprobe.blacklist=hid_asus on the kernel command line makes the keyboard work at the login screen (Fn+F2/F3 still do not work). Expected: keyboard works at the login screen and Fn+F2/F3 work, as in 6.12.107. Please let me know if I can test anything else. Thanks, Facundo *--FACUNDO M.
